BSides Knoxville 2025

The May 9, 2025 East Tennessee security conference in Knoxville. Its official guide says Fox Pick made the year's badges; a public Fox Pick maker talk later documents the ESP32-S3 electronic artifact, while no public recipient allocation, direct source-repository URL, or rights-cleared badge image has been recovered.

BSides Knoxville 2025 Fox Pick ESP32-S3 Badge

BSides Knoxville's 2025 official guide says Fox Pick made the event badges. In a public post-event talk, a Fox Pick representative describes the resulting electronic badge as ESP32-S3 based, with Bluetooth Low Energy and 2.4 GHz Wi-Fi, an SSD1309 display, capacitive touch controls, USB-C, a CH340 USB-UART bridge, battery voltage monitoring and charging/protection circuitry, a NeoPixel status light, and exposed I/O pads. The talk says source code was made available through a QR-linked GitHub page, but this pass did not recover a direct repository URL.

Issues & Camp Impact

BSides Knoxville 2025 Fox Pick ESP32-S3 Badge note

distribution and production boundary · official guide plus public maker talk · artifact and maker relationship documented; allocation unresolved

The official guide says Fox Pick made the badges, and the public talk discusses high-volume manufacture, but neither reviewed source gives an exact unit count, recipient list, ticket tier, pickup record, variant inventory, replacement policy, or attendee-wide allocation statement.

The record documents a real event-linked electronic artifact without treating the existence of badges or a manufacturing account as proof that every attendee received the same finished device.

BSides Knoxville 2025 Fox Pick ESP32-S3 Badge note

hardware specification boundary · maker-documented summary only · component-level overview public; engineering archive absent

The public talk names the ESP32-S3, display family, interaction and power features, but does not publish a board revision, PCB dimensions or artwork, schematic, Gerbers, BOM, exact display configuration, battery chemistry or capacity, component substitutions, radio certification, test results, or final production configuration.

The catalogue preserves the documented board-level surface without presenting a talk summary as a complete hardware specification, manufacturing record, safety assessment, or reproducible design.

missing rights-cleared image · local project policy · needs licensed original replacement

No BSides Knoxville 2025 Fox Pick ESP32-S3 Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

technical archive and source-release boundary · public maker talk and source recovery · maker states QR-linked source; direct archive unlocated

Morgan Rogers' talk says source code was made available through a QR-linked GitHub page, but this pass did not recover the destination URL. No source license, repository ownership record, source snapshot, release/tag, build instructions, final binary, schematic, Gerbers, BOM, or board files were recovered.

The catalogue can retain the maker's source-release statement while avoiding a fabricated repository link, open-source license claim, reproducible build claim, or unsupported source-code detail.
